Unable to push to sregistry via command line

[659-bit]

Hi,
this is my first bug report on Github, so please tell me, if I missed anything. :)
We encountered the following problem with our Sregistry installation:
When pushing images to the sregistry via the command line from another host, we receive an http status code 500:

$ singularity push -U cow_latest.sif library://user.name/test/cow:test
WARNING: Skipping container verifying
 0 B / 87.95 MiB [-------------------------------------------------------------------------------------------------------------------------------------------------------------------]   0.00% 0s
FATAL:   Unable to push image to library: request did not succeed: http status code: 500

However, uploading the same images via browser and pulling them images via the command line works without problems.

Sregistry version: 1.1.18

That looks like a very old version - and I think I might recognize that bug from a long time ago (but can't remember the issue). Could you please try a newer version, 1.1.32 is the current? I believe that but was fixed.
